capwap: add capwap support
CAPWAP stands for Control and Provisioning of Wireless Access Points. CAPWAP is a standard, interoperable protocol that enables a controller to manage a collection of wireless access points. There are three drivers in Kernel Space: CAPWAP Domain driver, CAPWAP Bridge driver and CAPWAP Tunnel driver. CAPWAP Domain Driver implements configuration for CAPWAP Domain, including PCD configuration and FQs setup. User must configure and initialize CAPWAP domain before CAPWAP Tunnel and CAPWAP Bridge works. CAPWAP Tunnel Driver is a misc device driver, which registers four misc devices for four CAPWAP tunnels: fsl-capwap-ctrl-dtls, fsl-capwap-ctl-n-dtls, fsl-capwap-data-dtls, fsl-capwap-data-n-dtls. The misc device provides file-operation to transmit/receive DTLS/non-DTLS packets. For example, read from the device fsl-capwap-ctrl-dtls can receive DTLS control packet; Write to the device fsl-capwap-ctrl-dtls can transmit DTLS control packet. The CAPWAP Bridge Driver is also a misc device driver; it can bridge packets between PCIe NIC and CAPWAP data tunnels. To support capwap drivers, there should be a shared ethernet port in dts file to use as CAPWAP Ethernet port.
